Final answer:
Each barrel of crude oil yields about 45 gallons of petroleum products including gasoline.
Step-by-step explanation:
Each barrel of crude oil yields about 45 gallons of petroleum products including gasoline. This increase in volume is due to refinery processing gain, similar to what happens to popcorn when it is popped.
Gasoline makes up the largest fraction of all petroleum products obtained. Other products include diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt.
Therefore, each barrel of oil yields approximately 45 gallons of gasoline.
